US Air Force: Don’t Worry About Those Weird Lights and Booms Sunday, It’s Just a Spaceship

If you’re in the vicinity of Vandenberg Air Force Base in California Sunday evening (Oct. 7), you might hear some strange booming and see some weird lights in the sky. But the Air Force would like you to know that there’s no need to worry; something entirely normal is going on — a rocket that heaved its way up into space will be falling back to Earth, correcting its trajectory with “multiple engine burns,” and then (if all goes well) settling comfortably back on its landing struts in the vicinity of its launch site.

The Air Force released the warning because, while Floridians have had ample time to grow comfortable with the spectacle of SpaceX landings, this will be the first attempt to land a Falcon 9 rocket on the West Coast. It will not, however, be the first launch from Vandenberg:

The rocket is currently scheduled to launch at 7:21 p.m. local time, carry the SAOCOM 1A satellite into space, and return to Earth shortly afterward.

According to a Facebook post by the Air Force’s 30th Space Wing at Vandenberg, “local residents” can expect to see something of the rocket itself as it returns to the base, while people as far as Santa Barbara, Ventura and San Luis Obispo counties may hear thunderclap-like sonic booms, depending on the weather.

SpaceX launched its Falcon 9 rocket from Vandenberg Air Force Base in California on Dec. 22, 2017, with bystanders on the ground getting a gorgeous light show.

Make the ISS Bathroom Less Disgusting

Space Poop

Space may be devoid of life, but us Earthlings are working hard to change that, especially when it comes to the bacteria growing in the International Space Station’s bathroom.

The ISS’s bathroom isn’t the cleanest place in the universe, which is a problem given that space travel can weaken a person’s immune system — and that antibiotic-resistant bacteria have already been found on board.

“Spaceflight can turn harmless bacteria into potential pathogens,” said Elisabeth Grohmann, a microbiologist at Beuth University of Applied Sciences Berlin, in a press release. “Just as stress hormones leave astronauts vulnerable to infection, the bacteria they carry become hardier — developing thick protective coatings and resistance to antibiotics — and more vigorous, multiplying and metabolizing faster.”

No-Stick Surface

To help keep any astronauts who may have forgotten to wash their hands safe, Grohmann and her team developed a new, antimicrobial coating made of silver and ruthenium that they call AGXX, according to research published Wednesday in the journal Frontiers in Microbiology.

To test it out, the scientists put an AGXX coating on the ISS’s bathroom door. After six months, they didn’t find a bacterial cell on the surface. Some bacteria emerged after a year, but the AGXX coating still hosted 80 percent less bacteria than an uncoated steel door, according to the research.

Get the Elbow Grease

In the same press release, Grohmann blamed the bacterial growth on dust and other things that could have gotten in the way of the AGXX, adding that none of the bacteria that did survive was particularly dangerous.

“With prolonged exposure time a few bacteria escaped the antimicrobial action,” Grohmann said. “The antimicrobial test-materials are static surfaces, where dead cells, dust particles and cell debris can accumulate over time and interfere with the direct contact between the antimicrobial surface and the bacteria.”

It may not be perfect over long periods of time, but anything that keeps astronauts’ space poop where it belongs is a step in the right direction as NASA and other organizations figure out how to travel deeper into space over longer periods of time.

Toyota Reveals ‘Self-Driving Electric Moon Car’ As Japan Prepares To Land Astronauts On The Moon

Japan is planning a moon landing for 2029 and wants its astronauts to explore the lunar surface in a vehicle built by Japanese automaker Toyota.

The Japan Aerospace Exploration Agency (JAXA) and Toyota announced Tuesday that it will collaborate on international space exploration, specifically on developing a manned, pressurized rover that uses Toyota’s fuel cell vehicle (FCV) technologies.

“Manned, pressurized rovers will be an important element supporting human lunar exploration, which we envision will take place in the 2030s, ” said Koichi Wakata, JAXA Vice President. “We aim at launching such a rover into space in 2029.”

JAXA, which earlier this month landed its Hayabusa2 probe on the asteroid Ryugu, is hoping the collaboration with Toyota will “give rise to intellectual properties” needed for international space exploration.

The lunar rover will also have solar panels, which will be useful in lunar daylight, which lasts for two weeks in each month.JAPAN AEROSPACE EXPLORATION AGENCY & TOYOTA MOTOR CORPORATION

An FCV is a type of electric vehicle that, instead of using a battery, uses a fuel cell of oxygen and compressed hydrogen, which react with each other to generate electricity. The zero-emissions technology is already used on Toyota’s Mirai vehicle. “Fuel cells, which use clean power-generation methods, emit only water, and, because of their high energy density, they can provide a lot of energy, making them especially ideal for the project being discussed with JAXA,” said Shigeki Terashi, Executive Vice President at Toyota. He also mentioned that Toyota’s automated driving technologies were part of the project.

Although the amount of fuel that could be taken to the moon would be limited, said JAXA and Toyota, the pressurized rover would have a total lunar-surface cruising range of more than 10,000 km.

However, Toyota’s ‘space mobility’ concept for the pressurized rover being studied by JAXA and Toyota is pretty small. It envisions a 6 meter by 5.3-meter vehicle standing 3.8 meters tall. That’s enough room for two people, say JAXA and Toyota, or four in an emergency. Toyota and JAXA also revealed that they have been jointly studying the concept of a manned, pressurized rover since May 2018.

The moon presents some special challenges for any vehicle. Gravity is one-sixth of Earth’s, and the lunar surface is pocked by craters, cliffs, and hills. “It is exposed to radiation and temperature conditions that are much harsher than those on Earth, as well as an ultra-high vacuum environment,” said Wakata. “For a wide-ranging human exploration of the moon, a pressurized rover that can travel more than 10,000 km in such environments is a necessity.” Wakata also stressed the need for a ‘Team Japan’ approach to space exploration.

ispace’s HAKUTO-R mission will launch on a SpaceX rocket in 2020 to orbit the moon and be followed by a mission to land on the surface in 2021.HAKUTO/ISPACE

That’s a message that appears to be finding favor. Japan Airlines-backed startup ispace last month announced that its HAKUTO-R mission will orbit the moon in 2020 ahead of a mission to land on the surface in 2021. An finalist in the ill-fated Google Lunar XPRIZE, ispace plans to map, and eventually recover, water ice on the moon and learn how to use it as a resource. If it can separate lunar water into hydrogen and oxygen, it could provide fuel for Toyota’s moon buggy, as well as for a self-sufficient moonbase, and even rockets.

Aside from Japan Airlines, HAKUTO-R’s corporate partners include Japanese national daily newspaper Asahi Shimbun and Japan NGK Spark Plug, which wants to test solid-state battery technology on the moon in 2021. Another is Mitsui Sumitomo Insurance, which last month announced a new lunar insurance service. “The availability of lunar exploration insurance will encourage new players to participate in the lunar industry by reducing the risk of entry,” said ispace founder Takeshi Hakamada last month. “With the ability to insure our landers and rovers, ispace and its customers will be able to concentrate on realizing our vision without hesitation.”
